Sentences with phrase «climate change on crop yields»

Based on many studies covering a wide range of regions and crops, negative impacts of climate change on crop yields have been more common than positive impacts (high confidence).

Negative impacts of climate change on crop yields have been more common than positive impacts (some positive trends are evident in some high latitude regions).

Temperature trends are therefore important for determining both past and future impacts of climate change on crop yields at sub-continental to global scales.

While many researchers have investigated the effects of climate change on crop yields, Blanc's study is one of the first to consider how a changing climate may shape the availability and distribution of water basins on which irrigated crops depend.

«Most modeling studies that look at the impact of climate change on crop yield and the fate of agriculture don't take into account whether the water available for irrigation will change,» Monier says.
